Hi Stephane,
Yes you are right I thought this meant the number of elements in the
structure but now I see from the base draft that it is the length of the
structure.
Since destination may have 1 or 2 elements I think that the following will
be enough.
struct {
RouteMode routemode;
OverlayLink transport;
IpAddressPort ipaddressport;
Destination destination<1..2^8-1>;
} ExtensiveRoutingModeOption
